4.3.5. FLUE TERMINATION POSITION
IMPORTANT INFORMATION
Install the flue in accordance to BS 5440:1 2008 Position the terminal, so
the products of combustion do not cause a nuisance. The flue is secured in
the wall using either sand and cement or heatproof silicone. The flue must
be supported by a bracket every meter of flue length and at every change of
direction.
Due to the high efficiency pluming will occur. For this reason, vertical
termination is recommended, and in any case, terminal positions which could
cause problems should wherever possible be avoided.
Care should be taken in the case of large multiple boiler installations and
complying with the requirements of the Clean Air Act. The information below
is extracted from BS. 5440 Pt. 1 and is for boilers with heat inputs not
exceeding 70kW nett, and the latest Building Regulation Part J. Detailed
reference should still be made to these standards. In IE refer to I.S. 813:2002.
